Problems solved by technology

[0003] Therefore, the defects of the traditional fresh air equipment in the operation process are mainly that the airflow purified by the fresh air equipment itself is clean when the fresh air equipment is ventilating and exchanging air. However, due to the operation of the fresh air system, the overall indoor environment and the outdoor environment The air pressure changes at any time. When the overall indoor air pressure is high, not only the fresh air system will output air to the outside, but also the high-pressure air will be discharged from the room through windows or door cracks; when the overall indoor air pressure is low, The outdoor airflow will enter the room through windows or door cracks. Since these airflows are air that has not been purified by the fresh air purification system, it will directly affect the actual indoor air environment. At the same time, the fresh air purifier itself greatly improves the indoor circulation mode. purification speed

Embodiment 1

[0023] Embodiment 1: as figure 1 with 2 Shown is a differential fresh air purifier, the fresh air purifier is a sealed housing 1, and the housing 1 is provided with an indoor fresh air outlet 5, an indoor return air outlet 4, an outdoor air inlet 2 and an outdoor air outlet 3, The housing 1 is provided with a heat exchange chamber 6, an air outlet chamber 9, a pretreatment chamber 7 and a post-treatment chamber 8, and the indoor return air outlet 4 and the outdoor air inlet 2 are respectively connected to the two ends of the heat exchange chamber 6. The indoor fresh air outlet 5 passes through the flow control valve T 1 It communicates with the post-processing bin 8 with the main fan 10 , the outdoor air outlet 3 communicates with the outlet bin 9 through the secondary fan 11 , and the pre-processing bin 7 communicates with the post-processing bin 8 .

[0024] The heat exchange chamber 6 of the present invention is provided with a plurality of uniformly distributed heat exch...

Embodiment 2

[0025] Embodiment 2: as figure 1 with 2As shown, the indoor air return port 4 and the outdoor air inlet 2 are provided with a coarse filter screen 16; the indoor return air port 4 and the outdoor air inlet 2 mainly use the intake air of the fresh air system, and here only need to pass through the coarse filter screen 16 Simply filter to prevent large particles of impurities or dust in the air from directly entering the heat exchange system.

Embodiment 3

[0026] Embodiment 3: as figure 1 with 2 As shown, there are a plurality of air outlets evenly distributed on the return air duct 15, and the return air duct 15 is connected to the heat exchange chamber 6 through the air outlets, and the inner circulation port is provided with a control air valve T 4 The main purpose of the return air pipe 15 is to ensure the working temperature in the shell side of the heat exchange chamber 6, so the indoor air return port 4 flows into the shell side of the heat exchange chamber 6 through the air return pipe 15 at a relatively high temperature in the room. The air flow is evenly distributed through the plurality of air outlets, so that the heat exchange chamber 6 maintains a uniform heat exchange temperature and ensures the heat exchange effect.

Abstract

The invention discloses a differential fresh air purifier and an operation method. The differential fresh air purifier is a sealed shell which is provided with an indoor fresh air inlet, an indoor return air inlet, an outdoor air inlet and an outdoor air outlet, and the shell is internally provided with a heat exchange compartment, an air outlet compartment, a preprocessing compartment and a post-processing compartment; the indoor return air inlet and the outdoor air outlet are connected to both ends of the heat exchange compartment respectively, and the indoor fresh air inlet communicates with the post-processing compartment through a flow control valve and a main fan; the outdoor air outlet communicates with the air outlet compartment through a secondary fan, and the preprocessing compartment communicates with the post-processing compartment; in the invention, the improved differential fresh air purifier structure is utilized, and the new operation method is applied to a control system so as to ensure that the indoor air pressure is higher than the outdoor air pressure, and the indoor air quality is stable; in the fresh air purifier, the heat exchange compartment is further improved, and convenient for heat exchange between indoor airflow and outdoor airflow which exchange heat through a baffle in the transmission process of a single heat exchange pipe; the contact time is long, and the heat exchange efficiency is high.

Description

technical field [0001] The invention relates to the technical field of indoor air purification, in particular to a differential fresh air purifier and an operating method thereof. Background technique [0002] The indoor fresh air purifier is a new type of household appliance, which has the functions of adjusting temperature, automatically detecting smoke, filtering dust, eliminating peculiar smell and harmful gas, double sterilization, and releasing negative ions. As an emerging air purification device, from its functional point of view, it is used for air exchange between indoors and outdoors, but as a normal living room, it cannot be sealed, and it is only ventilated by fresh air equipment. , the windows, doors or various gaps in the living room are all indoor and outdoor ventilation paths. [0003] Therefore, the defects of the traditional fresh air equipment in the operation process are mainly that the airflow purified by the fresh air equipment itself is clean when th...
